Hi folks

I'm having a random problem, when i'm capturing video using guvcview,
sometimes, the sessions is closed.

Taking a look on Xorg.0.log I'm seeing a segmentation fault.

Could anybody address me where is the best place to find out a solution for
that ?

Bellow are the latest lines of Xorg.O.log.old.
